Aquarius S.A.L offers its clients a wide range of water treatment applications, and depending on the quality of the original water and its final use, we implement the appropriate treatment, amongst the ones listed below:

1.

Softening system

Water is referred to as “hard” when it contains more minerals (namely calcium and magnesium) than ordinary water;

the degree of water hardness increases as more calcium and magnesium dissolve. Removal of these minerals is accomplished by softening the water through an ion exchange process. It is a crucial process since it has a direct impact on our daily life.

Below are some examples of the numerous inconveniences of hard water:

Harsh on the skin.

Scaling in boilers, heat exchangers, industrial equipment and other devices.

Requirement for more soap and synthetic detergents for home laundry and washing.

Clogging of the pipes.

As a specialist of water softening systems, Aquarius S.A.L has designed and installed more than 1,500 water softening plants, of different dimensions and uses.

We always make sure that every treatment plant we deliver to our clients is of superior quality.

2.

Water filtration

Filtration is a mechanical or physical process consisting in the separation of solids from liquids (separating particles in the feed from the resulting filtrate). Although it is the oldest method of filtration, it is still widely used today in municipal and industrial water treatment.

All our filters are designed to give operational advantages and are characterized by high performance and long life. We supply a wide range of filters for both municipal and industrial use, and customize our filters according to our clients’ needs. Our range consists of filters in stainless steel, steel epoxy coated and fiberglass composite, and the flow rate of our filters varies from 1 m3/h to 200 m3/h.

3.

Activated carbon filtration

Carbon is a very porous material with a big surface; activated carbon is the most powerful adsorbent. The two most common types of raw materials used to produce activated carbons are coconut shell and bituminous coal. Activated carbon filtration can be used in the industrial and municipal fields. The most popular forms of activated carbon are powder activated carbon (PAC), and granular activated carbon (GAC). Here are some of the components removed by the activated carbon filtration process.

Although water is abundant, the potential drinking water represents only 0.3% of the world’s total quantity. The sources of potable water are multiple and include well water, precipitation (rain, snow, etc.), municipal water, and surface water such as rivers.

Depending on the source and quality of water, Aquarius S.A.L will propose the corresponding solutions to its clients. An array of treatment processes is available and includes: filtration, microfiltration, ozone generators, ultra-violet sterilization, chlorination and reverse osmosis system. Following are some of the used processes:

Ultra-violet sterilization

Ultra-violet is a sterilization method that uses ultraviolet light to remove harmless microorganisms (such as bacteria, viruses, algae and protozoa) from the water.

UV light has the ability to affect the function of living cells by altering the structure of the cells nuclear material, or DNA. This method of treatment penetrates and permanently alters the DNA of the microorganisms, and is environmentally friendly, since it does not use any chemicals to disinfect the water. We propose ultra-violet sterilizers for small residential applications as well as large commercial and industrial projects.

The discovery and benefits of ozone dates back well over 150 years. Recent developments in technology have allowed a new generation of applications and products, using ozone to emerge.

Ozone (O3) is created when diatomic oxygen (O2) is exposed to an electrical field or UV light. Exposure to these high levels of energy causes a portion of the diatomic oxygen molecules to split into individual oxygen atoms, which combine with diatomic oxygen molecules to form ozone. It is an extremely powerful oxidant and disinfectant. Today, ozone is used in several applications: drinking water, beverage, bottled water, industrial effluent, etc.

The utilization of ozone has many advantages:

Very high oxidizing power with very short reaction periods.

Does not leave unpleasant chemical taste or smell.

Does not add chemicals to the water.

Efficient over a wide pH range.

Chlorination

Chlorination is another method used by Aquarius S.A.L to disinfect potable water. Chlorine is often the disinfectant of choice as it is reasonably efficient, cheap and easy to handle. It is a powerful germicide, killing many disease-causing microorganisms in the water, reducing them to almost non-detectable levels. Chlorine also eliminates bacteria, molds and algae that may grow in water supply systems.

In all but the smallest water treatment plants, chlorine is added to water either in aqueous solution or chlorine gas. Smaller supplies may use tablets of hypochlorite. Chlorine is also used as a disinfectant in several fields other than potable water: domestic water, swimming pools, fountains, etc.

5.

Iron removal

Making up at least 5% of the earth’s crust, iron is one of the most plentiful resources. Although it is not considered hazardous to health, a level above 0.3 mg/l could have negative implications. For instance, when the level exceeds this value, we may see brown, red or yellow stains on laundry, dishes and household fixtures. It might also lead to water having a metallic taste and offensive odor, and water system piping and fixtures becoming restricted or clogged.

Aquarius S.A.L proposes a variety of solutions to remove iron from the water. There are no standards rules, but a specific solution or process for each situation.

Here below are some of the processes used for iron removal:

Chlorination: chemical oxidizer is used to convert soluble iron to an insoluble form, before it is filtered.

Birm filtration: acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and dissolved ferrous iron.

Aeration: Oxygen is introduced into the water to convert soluble iron into insoluble form.

Greensand filtration: soluble irons are oxidized by contact with higher oxides of manganese on the greensand granules.

6.

Demineralization

Demineralised water, also known as deionised water, is water that has been purified by removing the dissolved minerals and salts such as sodium and chloride. Deionization uses ion exchange resin to exchange minerals salts (hydrogen for cationic ions and hydroxyl for anionic ions).

Years ago, high purity water was used only in limited applications. Today, deionized water has become an essential ingredient in hundreds of applications including: pharmaceuticals, autoclaves, chemicals production, medical facilities, electroplating, food and beverage, leather goods processing.

Deionizers are regenerated with dilute acid (sulphuric or hydrochloric) and alkali (sodium hydroxide) solutions requiring local storage of chemicals.
Aquarius S.A.L has both the experience and expertise in demineralization systems to provide our clients with the best technical solutions.
